I was not paying attention. DTD this morning without preventative measures because I believed myself to be in the safe zone. Literally just now Decided I should start charting (not temping) just to keep track of AF and projected O days. And ooppppssss, I have O'd many many a times at CD 14 and today is cd 12. I am still spotting from AF (well, it's like tinted cm)so I think that just threw me off. Here's to waiting!
